If you said Iowa, South Dakota, and New Mexico, well done. If you had Texas or California in there, fair enough — but neither of those clean-energy behemoths made it onto the podium, per the latest report from trade group American Clean Power Association.
Of the electricity produced in Iowa last year, 61% came from wind and solar — and pretty much all of that was wind. For decades, the state has been a leader on wind energy, though in recent years, development of new projects has dried up because of mounting local opposition and the Trump administration’s broader attacks on renewable energy.
South Dakota is a similar story, at 59%. Consistently gusty weather and ample land have led the state to install lots of wind turbines, and solar is scant in comparison.
New Mexico, which got about half its electricity from wind and solar in 2025, is a bit more balanced. Wind accounted for 36% of its power, and solar for 17%. The state is also a leader in grid batteries, which it is building out quickly to save more renewable energy for periods when the sun isn’t shining and the wind isn’t blowing.
The leaderboard could soon change as some states charge toward ambitious 2030 clean energy targets. California, for one, saw a massive leap in renewable energy production last year, with solar and wind accounting for 44% of its generation. The year before, that figure was 38%.
